摘　　要：以“齐达利”番茄为试材,探究3种氨基酸对设施番茄根系及植株生长的调控影响。结果表明,与对照处理相比,供试3种氨基酸均能促进番茄植株及根系生长;在结果期,组氨酸、酪氨酸、复合氨基酸处理番茄地上部生物量分别增加14.19%~33.26%、24.88%~37.91%、34.42%~40.93%;果实生物量分为增加32.17%~49.57%、42.17%~68.70%、40.00%~71.30%;在开花-结果初期,各氨基酸0.50 g/L质量浓度处理下根体积、根表面积、根总长度、根尖数与对照处理均差异显著,促生效果极好。在开花-结果初期根系生物量各氨基酸以高浓度处理较优,在结果期根系生物量随氨基酸施用浓度增加呈递减趋势;建议在开花-结果初期施用氨基酸质量浓度为0.5 g/L,结果期调整为0.1 g/L。Tomato“Qidali”is potted in greenhouse,the regulation effects of single amino acids on the root system and plant growth of facility tomato are studied.The results show that,compared with the control without amino acids,the three kinds of amino acids can promote the growth of tomato plants and roots.At the fruiting stage,the aboveground biomass of tomato treated with histidine,tyrosine and complex amino acid are increased by 14.19%-33.26%,24.88%-37.91% and 34.42%-40.93%,respectively.Fruit biomass are increased by 32.17%-49.57%,42.17%-68.70% and 40.00%-71.30%.At the initial stage of flowering to fruiting,the root volume,root surface area,root total length and root tip number of 0.5 g/L amino acid treatment are significantly different from those of CK treatment,and the growth promoting effect is excellent.At initial stage of flowering to fruiting,high concentration of amino acid is the best treatment for root biomass.At the fruiting stage,the root biomass of tomato decreases with the increase of amino acid application concentration.It is suggested that the concentration of amino acids is 0.5 g/L at initial stage of flowering to fruiting and adjusts to 0.1 g/L at fruiting stage.
